MdeModulePkg: enforce arch-specific alignment for split regions 

The splitting of memory regions into code and data regions violates
architecture specific alignment rules by using a fixed alignment
of 4 KB. Replace it with EFI_ACPI_RUNTIME_PAGE_ALLOCATION_ALIGNMENT,
which is defined appropriately on each architecture.
